Abstract

Efforts in the improvement of work conditions in factories focus mostly on issues related to health ' protection' . Health ' promotion' however, is one of the issues which has drawn little or no attention among factory managers and health authorities. It is now more than a hundred years that manifests are issued and pledged by employers addressing health promotion among workers.Although such statements have for long bounded employers by limitations and standards on hazardous risks. Researches on promoting the workers health are mainly very little and the real actions in this regard are even less than that. One of the early studies in this issue took place by Diana Chapman Walsh, Susan E. Jennings, Thomas Mangione, Daniel M. Merrigan which the result was published in Journal of Public Health Policy in 1991. The article entitled "Health Promotion versus Health Protection? Employees' Perceptions and Concerns." This is an interdisciplinary project to control and harmonize the machinery noises of textile factories. In this project Jamineh and Zantous textile factories in Tehran have been chosen as pilots in which the noises of the sewing machines have been studied and tried to be controlled and tuned in specific frequencies in order to reach an overall harmonized noise. To do this, in the first step the sources of the noises were distinguished. In the second step, the noise of every machine was individually calculated and the spectrums one by one were drown and fully studied (the software used in calculating and analysing the sound is 'Transcribed' produced by Seventh String company). As the final step, the frequency in which most machines were shared was set as the basis of the harmony and the noises of the rest of the machines were tuned in particular consonance intervals of such basis. For instance if in one section of the factory there were four sewing machines working next to each other and the overall noise of each of which were G, S, G, G quarter sharp, A, the basis note considered as G. In this example, the machine with G sharp noise changed to overall G and machine with overall A noise moved to another section of the factory to harmonise with some other machines. The overall frequency of machines influenced by various factors, some of which very difficult to find their sources. In this project in the first phase it was tried to detect the main generator of the noise and in the second phase various approaches used to control it by lowering or raising the frequency in order to reach a specific note which was in consonance with other machinery noises. Prior and after the project questioners were field by workers to study their satisfaction with tuned noise. The outcome showed that the satisfaction of the workers with the tune noise was significantly higher than the wild noises of machines before the project taking place.
